我收到java.sql.SQLException：当尝试访问存储过程（在oracle中创建）时，在索引:: 2时缺少IN或OUT参数，该存储过程具有客户端名称（varchar）作为输入参数＆amp; cursor作为输出参数。当我通过JSP页面测试它时会出现错误，但是当我通过Junit测试stroed proc时，我没有收到错误。所以我很困惑。请在下面找到我存储的proc＆amp;还有正在通话的DAOImpl类。我可以看到JSP页面正确地将名称从输入文本框传递到存储过程的名称输入参数。

以下是我的JUnit测试，它提供了适当的数据
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"classpath*:test-applicationcontext.xml"})
public class ECIDFetchServiceTest {
@Autowired
ECIDDetailsDAOImpl ecIDDAO;
@Test
public void validategetECIDDetails() {
List<ECIDDetails> ecidDetails = new ArrayList<ECIDDetails>();
ecidDetails = ecIDDAO.getECIDDetails("ABN");
assertNotNull(ecidDetails);
assertTrue(ecidDetails.size() > 0);
}
}
嗨Priyesh，
我正在使用JSF来创建UI。请在下面找到必要的代码。
JSF代码
<h:panelGrid columns="3" cellspacing="5" cellpadding="5">
<h:outputLabel value="Elementary Client Name" />
<h:inputText value="#{ecIDBean.elementaryClientName}" />
<h:commandButton value="Get EC" action="#{ecIDBean.executeEcIDList}">
</h:commandButton>
</h:panelGrid>
托管Bean类
public class ECIDFetchBean {
private String elementaryClientName;
private List<ECIDDetails> ecIDList;
private ECIDFetchService ecIDFetchService;
public ECIDFetchBean() {
ApplicationContext ctx = ApplicationContextProvider.getApplicationContext();
ecIDFetchService = (ECIDFetchServiceImpl)ctx.getBean("ecIDFetchService");
}
public String getElementaryClientName() {
return elementaryClientName;
}
public void setElementaryClientName(String elementaryClientName) {
this.elementaryClientName = elementaryClientName;
}
public List<ECIDDetails> getEcIDList() {
return ecIDList;
}
public void setEcIDList(List<ECIDDetails> ecIDList) {
this.ecIDList = ecIDList;
}
public void executeEcIDList() {
ecIDList = ecIDFetchService.getECIDDetails(elementaryClientName);
}
}
服务类
public class ECIDFetchServiceImpl implements ECIDFetchService {
private ECIDDetailsDAO ecidDetailsDAO;
public List<ECIDDetails> getECIDDetails(String elementaryClientName) throws OCRReportingException {
return ecidDetailsDAO.getECIDDetails(elementaryClientName);
}
嗨Priyesh，
JSP也指向同一个数据库。我改变了我的DAOImpl类来调用存储过程 SimpleJdbcCall＆amp;它现在从JUnit和JSP都运行良好。
public List<ECIDDetails> getECIDDetailsBySimpleJDBCCall(String elementaryClientName){
SimpleJdbcCall simpleJdbcCall = new SimpleJdbcCall(dataSource);
simpleJdbcCall.withCatalogName("ncr.pkg_ocr_gui").withProcedureName("sp_get_client_details_by_name")
.withoutProcedureColumnMetaDataAccess()
.declareParameters(new SqlParameter(EC_ID_NAME_PARAM, java.sql.Types.VARCHAR),
new SqlOutParameter(ECID_CUR_TYPES, OracleTypes.CURSOR, new BeanPropertyRowMapper<ECIDDetails>(ECIDDetails.class)));
MapSqlParameterSource sqlParameterSource = new MapSqlParameterSource();
sqlParameterSource.addValue(EC_ID_NAME_PARAM, elementaryClientName);
Map<String, Object> results = simpleJdbcCall.execute(sqlParameterSource);
List<ECIDDetails> ecidDetails = (List<ECIDDetails>) results.get(ECID_CUR_TYPES);
return ecidDetails;
}
